Special plastic materials, with thermoplastic polymers or duroplastics used as impregnating materials for glass fibres or carbon fibres.

The fibres can be textile, mineral or synthetic,
woven or inserted, according to specific shape
and resistance features of components required.
Compound components are obtained with specific forming tools. Sometimes, such components are obtained by machining of customized blanks

The main advantage of compound materials is the excellent ratio weight vs. rigidity
